The importance of the retention sleeve becomes conspicuous when the rotor suffers from the radial and tangential stresses derived from a high speed say 60 krpm. With respect to the mechanical property of Titanium, this material has been demonstrated that it could be a proper material for the retention sleeve. The investigations of this paper are concentrated on the electromagnetic coupled with mechanical design of a 2-poles, 18-slots, 40 KW HS-PMSG which is carried out through FEM analysis using JMAG 17.1 and ABAQUS CAE and optimized through the well-known Taguchi optimization method. The obtained results assure the robust mechanical behaviour of the HS-PMSG at a rotational speed of about 60 krpm meanwhile the cogging torque, the Joule loss, and the total weight of the optimally designed HS-PMSG are reduced 44.71%, 27.87%, and 2.78%, respectively compared with the initial design. %U https://www.ije.ir/article_137604_d45f7d38d875b63a99143081fc2eac18.pdf
